Announcements

• Graded Exercises are now recorded for the PI chapter. If you have any "zeros", you can make them up for partial credit. When they are removed from your Schoolwork, they will be here on the wikispace.
• PI Study Guides are due today. You can "share" them with me if they are a GoogleDoc, or email them to me at my umasd.net or umasd.org address. (DO NOT message me on MyBigCampus any more!)
• Your Friendship Detector will be due on Tuesday, 3/25. (Two weekends between now and then!) Next steps:
  • Get your Friendship Logic Sentence cleared by me. Check your G-Mail to be sure that your statement is clear. Reply to the G-Mail if necessary.
  • Complete your Friendship Truth Table, introduced in class this week. You can find another copy on my Teachers folder, or in the GoogleDrive folder we share. Show me when you think it matches your Logic Sentence.
  • Work on your Friendship Wiring Diagram. You could create the wiring from scratch, using the Circuit Construction Kit (CCK from PhET), or try my sample diagrams online .

Introduction to Wave Motion

• The next chapter studies "Transmitting Information". We will focus on waves, both sound waves and radio waves.
• Some waves move very fast. Today, we will study slower waves, using a Giant Slinky.
